Extensions- 17 Nov 2025
Freddie, Kaz and Dan are a great team. I felt they were friendly and professional throughout. Any slight niggles were discussed and solutions found, quickly and professionally. They were respectful and went out of their way to get on with all the neighbours. Over all I would say they are a team of very nice people, who care about what they do and take pride in achieving the result their clients are after.

I was very pleased with this company so much so that they are starting a new job for me November 15. The building firms carried out a full loft conversion for me installing bathroom, brickwork, joinery, plastering, Roofing and installation of windows and double glazed doors. I have high standards and want everything to be completed in the same way, the workmen respected my home and always left if clean. My main contact was with the owner of the company Dwight Lynch, he was very flexible and Nothing was too much for him to do. He has an attitude which I like in a builder "customer not always right but must be happy" he provided me with ideas along the way and where things did not go to plan due to my own instructions he worked around the issue and provided suitable alternative options. I was very happy with the pricing of the job and feel that certainly I would recommend him and also I would use him again. He and his workmen were all trust worthy and I gave them keys to my house to carry-out work whilst I went on holiday. I had no concerns when I came back everything was as I left it.

An extension builder in Gatwick should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Gatwick extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Gatwick?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Gatwick extension builder’s ability to deliver a result that meets your expectations.
